Which diagram is used to show the population's age and gender structure?

• A. Age pyramid
• B. Population pyramid
• C. Demographic chart
• D. Gender-age diagram

Answer: (A)

This diagram is all about showing how many people there are in each age group and how many are male or female. An age pyramid uses age groups along with two mirrored bars for genders, so you can quickly see the shape of the population—whether there are lots of young people, or many older people, and how the male and female numbers compare in each age band. That direct display of both age structure and gender distribution is what this diagram is meant for, making it the best choice for describing the population’s age and gender structure. The other terms are less standard or too vague for showing this specific pattern.
